This study examines the impact of the Corona Virus Disease 2019 (COVID-19) pandemic on Energy Consumption in relation to Human and Environmental Responses in Ontario Canada. Supply and demand of Electricity which is a secondary form of energy was extensively studied and reviewed. This impact was compared between the active COVID-19 period in the study area and similar periods of previous years. The data sets studied, reviewed and analyzed were extracted from the database of the World Bank World Development Indicator and the Independent electricity System Operator (IESO) of Ontario Canada. From the study and analyses, it was evident that: COVID-19 has disrupted many businesses, resulting in reduced provincial demand/Consumption and creating significant uncertainty in supply and demand forecasts. Demand reductions in all hours ranging from 800 -3,000 MW, which is 6 -18% of typical demand for the similar periods/time of the year. Industrial and Commercial consumption were drastically reduced due to the closure of majority of the factories and industries as a result of the COVID-19 pandemic. This also led to the reduction in the Green House Gas and Co2 emissions in the studied period of active COVID-19, compared to similar periods of previous years. As expected, Residential and household demand experienced some increase because of the stay at home rule that was employed to manage social distancing concept for the COVID-19 period. An all-inclusive stakeholders dialogue is especially important during periods of uncertainty to ensure stable maintenance and reliable operation of the grid.
